Couple old ratchets, need info please

[alinc100]

Hi All,
Picked up a couple older ratchets at an estate sale along with some other items.
I would like to find out more about these two ratchets as i have not seen anything like them before.

First one is marked N0-2888,no other markings other than "oil" at the hole by the gears.

Second one is marked in raised letters ADI-I or maybe AD1-1 and stamped on the opposite side AMMCO.

Thanks for looking,
Andy

The first one is a familiar design. Perhaps an old SK or Blackhawk. Alloy Artifacts will have the info you want.

Ammco makes brake tools. I've never seen anything like that one. Perhaps it was a tool for one of their brake machines.

Thanks for the info,I have two inserts for it one for 3/8" and one for 1/4''
I presume the 1/4" one might not be original but it fits and I will keep it with the ratchet.
